' Application filed May To all whom a Be it known a flume, and the p I iron, or other hard foreign substance, not infrequently causes damage and annoyance invention is to provide for catching the stones and to so arrange etc., may the flume without interfering beetsfor any material An object of my an improved means or other foreign matter,

cleaned from with the'flow of the riod of time. The-distinguishing features of my invention and the important structural elements characterizing the preferred embodiment which is illustrated as an example, more particularly explained in the specific description hereinafter to be given.

Reference is to be had to the accompanying drawings formin a part of this specification, in which simi ar characters of reference indicate'corresponding parts in all the views.

Figure 1 is a plan view of my improved device interposed in a flume; Fig. 2 is a longitudinal vertical section on about the line 2-2 of Fig. 1; Fig. 3 is a cross section on about the line 3-3 of Fig. 2; and Fig. 4 is a fragmentary end view showing the dog for holding the device in position. In the illustrated practical embodiment of my invention, a flume section is constructed comprising a concave pocket 10, the ends 11 of which have openings 12 that receive end portions 13 of the flume, the ends 11 desirflanges 14 on which the flumesections 13 rest.

ing members. posed advantageously at diametrically opposlte sides of the shaft 19, and sweep or Hume-clearing blades 21 are provided, and alternate with the conduits 20 around the shaft. The blades 21 may be integral'with each other and consist of plates 22 spaced at the center by blocks 23 and secured to the shaft 19, as by bolts 24:, that pass through the plates 22 on opposite sides of the shaft through the intermediate blades 23 and through-the shaft 19. The conduits 20 may consist, as illustrated, of aplate" bent into arched form, the inner ends of the plate belng flanged, as at 26, and riveted, as at 27, to the plates 22. Desirably the meeting ends of the respective blades 21 are riveted to each other at the outer edges, as at 28. On one trunnion 18 is mounteda collar 29 having teeth 30 for the application of a lever or other tool, to rock or turn the shaft 19. Each conduit 20 is formed with outlets 31 in the bottom thereof for the escape of stones or other hard substances, and at each outlet deflecting plates 32 are provided and inclined inwardly, the said plates extending partially over the opening. The necessity tion will depend on the rapidity of the flow of the water passing through the flume sections 13. If the flow is n t rapid, then the deflecting plates 32 cause the upward so as to be carried by the stream beyond the outlet 31. On the other hand, if the flow of the stream is very rapid, the beets will move over theoutlet so rapidly as not to drop therethrough. Stones, however, that move more the bottom ofthe conduit in contact therewith, will drop through the ditional deflecting plates 33 may be provided, rojecting outwardly at the outlets 31, at t e end opposite the deflecting plates 32 to direct the stones downward intothe pocket 10 to the bottom thereof. The arrangement is such that the bottom of the conduit will be substantially in line with the flume sections 13 and spaced a sufficient distance above the bottom. of the pocket 10 to provide the necessary space for the collection of stones, etc.

When the shaft is rocked or turned. the conduit section in the pocket will be moved transversely of the flume, while the conduit I that was uppermost will be moved into posi- Thus conduits 29 are disslowly and roll over outlet 31. Ad-

stones, etc., upward to one side of the pocket,

tion in linewith the flume-sections, so that the pocket that was previously in action may be cleaned, while the other conduit is in position. Thus the flow of the beets need not be interrupted while the conduit is being cleaned. The rocking of the shaft also, swings the clearing blade 21 downward and transversely of the flume so that the stones and other matter in the pocket 10 will be raised upward, the said blades havconduits 20, and moved in .a path close to thewall of the blades 21 serve to carry the from which the stones are thrown onto a grating 35, provided adjacent 'to the flume, the grating being usually arranged over a sewer, or the like.

The collar 29is formed with recesses 29. for receiving dog or catch 40, which may be pivoted, as at 41, to theend 11 of the pocket, the said dog having a tooth 42 on its under sideto engage between the teeth 29, for holding the shaft 19 and the elements carried thereby inposition.
